Veritas -- do # of spindles really matter ??

Regarding Oracle 7.3.4 running on Solaris 2.6 with Veritas: The database was originally architected across 2 spindles, recommended by the SA. The DBA argued that more spindles should have been configured, allowing for separate data and index tablespaces, separate tablespaces for high-growth objects, toggled rollback segments, mirrored redo logs, etc., to minimize I/O contention as usage grows. The SA indicated that the 2-spindle architecture is sufficient, given that Veritas/RAID stripes each written data block across 5 physical disks anyway.
The question:
[Quoted] [Quoted] Which is faster -- (a) the current 2-spindle architecture, or (b) if 5
[Quoted] [Quoted] separate filesystems were explicitly-defined on their own dedicated disk?
[Quoted] [Quoted] Keep in mind both (a) and (b) would take advantage of the same Veritas/RAID
configuration (striping and mirroring).
